Isn't bun also written in rust, so can you clarify what your point is here?
replyDeno wasn't doing well and was repeatedly outperformed in downloads and raw performance when Bun was written in Zig, and even before Bun got acquired by Anthropic.
replyMy point is, even if Bun stayed on Zig, Deno still struggled to compete regardless of the language used.
I'd guess Deno failed because of the original decision of not supporting node_modules, instead went with a different way of handling dependencies. Else the native typescript support would most likely had pushed them to bigger success past nodejs.
replyThough nodejs was even then quite solid in it's position, so maybe it would not have made a difference.
